PLOW.

SPECIFICATION forming part of lLetters Patent No. 223,987, datedFebruary 3,.I88.

l Application led J une 30, 1879. I

To all whom it may concern:

Be it known that I, JOHN B. BRUCE, of Sunny Dale, in the county ofSedgwick and State of Kansas, have invented certain new and usefulImprovements in Plows; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference bein ghad to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention consists in a peculiar-shaped standard for supporting themold-board and other parts of the plow, and in a brace-bar arranged onthe land-side of the plow and attached to the standard and beam, and inother mechanism, all of which will be hereinafter fully explained.

In the drawings, Figure 1 is a side elevation of a plow constructedaccording to my invention. Fig. .2 is a side elevation of the castingwhich supports the `mold-board and other attachments. v

b is the casting, of peculiar shape, made to support the mold-board andotherattachments. It is formed of the front standard, bf, and rearstandard, b2, which have their upper ends connected by the plate b3.

Projecting horizontally7 and laterally from the upper edge of the plateb3 is the ange b4, made in such form as to it snugly against the underside of the beam a, to which it is fastened by bolts c.

The lower end of the front standard, b,is inclined forward, so that i-twill have the same pitch as the front edgel of the mold-board.

The rear standard is slightly inclined to the rear, and' has journaledin the lower end a small roller, d, placed on the land-side of the plow.Y

VThe mold-board e may be made in a sepa rate piece of proper form andsecured to the front edge of the standard b by bolts b5. AWhen thus madeit may be removed at will, or it may be cast with the standard b', astaste may dictate.

f is a brace made in the angular form shown.

The forward end of its under arm is secured to the lower end of thestandard b', while its central or elbow portion is secured to the lowerend of the standard b2, and the `upper end of its rear or vertical armis secured to the beam a in rear of the fastenings of the casting b.

To the inner side of the brace-bar f is secured a roller, g, which maybe removed and set at any desired point along said bar, which isprovided with bolt-holesf for this purpose.

The rollergis designed to run inthe furrow and serve as a fulcrum orrest by which the set of the point maybe regulated. It also aids inpreserving the set of the point, so that it will run at a uniform depthat all times.

The casting b is, by preference, made in a separate piece, having themold-board and other parts secured thereto, as indicated. f

1f desired the moldboard e may be detached, and a shovel having suitablelugs on its rear side may be attached.

This improvement is designed more especially for light work, such asmarking ground for planting, or where shallow plowing only is required.

The parts may all be made light. The rollers d and g give steadiness tothe movements of the device, and the brace, secured as described, givesstrength to the arrangement of parts and transfers to the beam anysevere strain or shock given to the front standard, b.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a plow, the casting b, constructed with the standards bl b2, top bar,b3, and horizontal iiange b4, and provided with the roller d, `journaledin the lower end of the rear standard,

d, the brace-barf, secured in a horizontal position to the lower ends ofthe standards b b2, and' having its rear end extended and inclinedVupward and secured to the rear end of the Witnesses:

WILLIAM FINN, MYRON E. GooDELL.
